Thanks for the clarification.

So, we can

1. Change org-latex-line-break-safe to "\\\\[0pt]%__ORG_EXPORT__",
   making it unique to distinguish Org-generated line breaks.
2. Establish a regexp criterion when it is safe to strip
   "[0pt]%__ORG_EXPORT__" from the page break (I am still unsure what
   will be the most reliable criteria here). If not safe, we just strip
   the "%__ORG_EXPORT__" part.
3. Write a filter that replaces the above from final output.
   Note: If we go __ORG_EXPORT__ way, it might be safe to leave the
   filter on by default as long as we can find a really robust criteria
   on when it is safe to drop [0pt] part.
